ZJ10B self-rescuer calibrator

Where is the compressed oxygen self-rescuer calibrator produced for coal mines B Self-rescuer tester Yunnan B Self-rescuer calibrator B Compressed oxygen self-rescuer tester price Spring is coming again, and it is the beginning of the mine. So are you ready? Okay, B. Have you got the compressed oxygen self-rescuer tester? Hurry up and grab it. Fortunately it's not too late yet.
B Test standards for the performance of the entire self-rescuer calibrator:
Test standards for the air tightness of the low-pressure system of the entire machine:
Negative pressure air tightness test, established in the respirator system Negative pressure, turn off the air source switch, keep it inside, and its pressure rises to the value.
For positive pressure air tightness measurement, close the exhaust valve, establish positive pressure in the respirator system, and maintain the pressure drop value
.
Oxygen supply (test standard for quantitative oxygen supply):
When the pressure in the high-pressure system is (~) and (~), use this tester to measure the quantitative oxygen supply.
Exhaust valve opening pressure detection group, component air tightness detection.
